The Block Up-Converter Ku-band 4W Verison 2 (BUC-Ku04 v2) is designed for operation in MVDS/MITRIS TV broadcasting systems according to standard DVB-S/S2 or DVB-C and operates up to 25 carriers. This device has PBR120 flange output and can be used with regular RRL or broadcast antennas. Supported modulation types are up to 32APSK, 256QAM. Stability of the output frequency and IMD3 level are very important for providing the modulation quality, so the local oscillator is locked by PLL with internal frequency reference. The device has the best linearity parameters in order to provide the lowest IMD3 level. The BUC-Ku04 v2 provides any 1000 MHz output bandwidth in Ku-band for 950 – 1950MHz input frequencies by order.

  • Typical LO frequencies (GHz):   8.8; 9.75; 9.8; 10.0; 10.6; 10.75; 10.8; 11.3; 11.8; 12.8; 13.05   (or by order)
